KK:
There are many things that can cause these conditions. Some common areas to check are the
ignition coils and plug wires. There is a good pic of what burned coil looks like in the 'how-to, tips...'
section of the site. You may also have a vacuum leak, or sticking injector(s). You need to have the
system scanned for codes first, so as to have a starting point for diagnosis.
